"The technicians of which one being the owner came out, measured the window, gave me a price and date for when the replacement glass should be ready.  The office called within the timeframe given to schedule the installation.  No issues with the installation and they were very friendly. My wife was comfortable with them around.  The installation was relatively quick.  They cleaned up after themselves any charge the price quoted.

"I was amazed. We had 10 new windows replaced, and after working a 10 hour day, I was dreading going home & cleaning for the next 10 hours. But when I walked inside my home you didn't even know they were there. everything was placed back to where it belonged, there was no mess to vacuum. There also was no mess outside, my garden was not even touched. The only thing I had to do was wash the windows and hang the curtains. They were very nice & polite, professional men who installed the windows. The windows themselves are 100% perfect. We could not be happier and could kick ourselves for not doing it sooner. They gave us a date in July for Installation. They arrived in May."

Glass Block Windows FAQs, answered by experts

You can still see vaguely into some types of glass block windows at night. Although there won’t be clear definitions, passersby may still see shapes, shadows, and movement through the glass. If you want complete privacy, consider installing diamond glass block windows rather than the typical clear or wavy glass blocks.

Their thickness depends on application, but most glass walls are typically 3/8 to 3/4 of an inch thick. Although it’s not as common, single panes of glass can also be 1 inch thick.

Glass block windows typically last for 15 to 30 years, which is slightly less than the 20- to 50-year lifespan of standard windows. You can extend their life by resealing them every few years. Professional installation is also key to ensuring the windows are placed correctly and will function properly for years to come. A professional installer will have the necessary skills, tools, and knowledge to install these features and can identify potential issues like damaged frames or cramped areas during a consultation.

Glass block mortar is the best choice for glass block window units. It is specifically formulated for glass block window installation. Glass block mortar is usually a mixture of Portland cement, sand, and special chemicals. It is a white mortar that is applicable inside and outside your home. Do not use regular tile mortar because it may not have the binding strength and flexibility required for glass block windows.

Heavy glass tends to be more expensive than thin glass because it is stronger and more durable. In most cases, ¼-inch-thick glass is ideal for mirrors, and ⅛-inch-thick glass is ideal for residential windows. Heavier glass isn’t always necessary, and can be more challenging to hang or install. Work with a local window installation pro for replacement or new construction windows.
